    Abstract: This disclosure is directed to a simulation system that verifies functionality and performance of an automated telecommunication cloud platform (“TCP”) which is used to configure hosts of cell sites and a mobile core of a 5G cellular network. The mock hosts are created with a required virtualization platform inventory of objects for implementing a 5G cellular network and registers the mock hosts with a mock centralized server management platform (“mock VC”). The mock hosts are used to simulate hosts of cell sites and a mobile core of a 5G cellular network using features of the TCP. Scale tests are used to verify functionality and performance of the TCP are performed on the mock hosts without any changes to the TCP.

    Abstract: The disclosure provides an approach for preventing the failure of virtual computing instance transfers across data centers. In one embodiment, a flow control module collects performance information primarily from components in a local site, as opposed to components in a remote site, during the transfer of a virtual machine (VM) from the local site to the remote site. The performance information that is collected may include various performance metrics, each of which is considered a feature. The flow control module performs feature preparation by normalizing feature data and imputing missing feature data, if any. The flow control module then inputs the prepared feature data into machine learning model(s) which have been trained to predict whether a VM transfer will succeed or fail, given the input feature data. If the prediction is that the VM transfer will fail, then remediation actions may be taken, such as slowing down the VM transfer.

    Abstract: A network interface controller (NIC) that includes a set of receive NIC queues capable of performing large receive offload (LRO) operations by aggregating incoming receive packets is provided. Each NIC queue turns on or off its LRO operation based a set of LRO enabling rules or parameters, whereby only packets that meet the set of rules or parameters will be aggregated in the NIC queue. Each NIC queue is controlled by its own set of LRO enabling rules such that the LRO operations of the different NIC queues can be individually controlled.

    Abstract: The disclosure herein describes an edge device of a network for distributed policy enforcement. During operation, the edge device receives an initial packet for an outgoing traffic flow, and identifies a policy being triggered by the initial packet. The edge device performs a reverse lookup to identify at least an intermediate node that is previously traversed by the initial packet and traffic parameters associated with the initial packet at the identified intermediate node. The edge device translates the policy based on the traffic parameters at the intermediate node, and forwards the translated policy to the intermediate node, thus facilitating the intermediate node in applying the policy to the traffic flow.

    Abstract: A centralized namespace controller allocates addresses in a distributed cloud infrastructure on-demand. Upon receiving a request to allocate addresses for a network to be provisioned by a cloud computing system included in the distributed cloud infrastructure, the centralized namespace controller allocates a network address that is unique within the distributed cloud infrastructure. Further, the centralized namespace controller allocates a range of virtual network interface cards (NIC) addresses that are unique within the network. The centralized namespace controller then allocates addresses from the range of virtual NIC addresses on an as-requested basis—when a virtual NIC is being created by the first cloud computing system on the network. Advantageously, by centralizing the allocation of addresses and dedicating independent NIC address ranges to different cloud computing systems, the centralized namespace controller enables stretched L2 networks between cloud computing systems while preventing duplicated addresses on the stretched networks.
